Torque
Description: Torque/force data scaling factor. In the SERCOS configuration this parameter defines the scaling
factor for all torque/force data in a drive. This parameter is only used when the preferred scaling is not selected in
parameter 86. In the analog configuration the scale factor is always 1.
This parameter is available with the 8720MC SERCOS interface.

Torque
Description: Torque/force data scaling exponent. In the SERCOS configuration his parameter defines the scaling
exponent for all torque/force data in a drive. This parameter is only used when the preferred scaling is not
selected in parameter 86. In the analog configuration the scale exponent is always 10-1.
This parameter is available with the 8720MC SERCOS interface.
